Based on a three-dimensional spatial measurement, several parameters to analyze quantitatively features of fracture surfaces different types of cementitious composite materials are presented. The parameters are ratio of real surface area to the projected area, interface area, orientation of facets in the fracture surface, surface fractal dimension, and line fractal dimension. Then the fracture properties and resisting mechanisms are discussed with relation to these parameters.
